Hello,

Noob here. My NABU came with short cable consisting of a 5-pin DIN to a TTL 5V to RS422 serial converter mini board with outputs of VCC, GRN, RXD, and TXD but the NABU onboard UA9637AC is already RS422? Looking to best understand how this would be connected to a USB serial emulator as all other videos I've seen have different pin outs and just use the DTech USB to RS422 Serial Port Converter connected directly to a 5 pin DIN without this TTL 5V to RS422 serial converter. So I just bought the adapter from Amazon, though I would like to still utilize what came with the system though it seems to be redundant.

The only way you could use that is if you bought additional hardware. You’d need to purchase a uart to usb adapter for that. I’m not sure who you bought it from but hopefully they didn’t try charging you for that adapter

Thanks for the info!

Darn, I was afraid it would require more hardware. Yup, there was a slight price increase as it was advertised indirectly as such, though no specifics on the adapter were given unfortunately. My assumption was that the person selling it at least knew enough. Well, lesson learned. Having an electronics background myself, after looking at the adapter and onboard ICs I was like grrrr.

I bought the standard gear from Amazon. A Monoprice MIDI Cable and a DTech USB to RS422 RS485 Serial Port Converter Adapter Cable with FTDI Chip.

Smoke check passed. I have some special plans for this machine. I'm online!
